To evaluate the body shape, we compute the per-vertex error on the high-resolution scan that is the uni-directional Chamfer distance from registered SMPL mesh vertices to the high-resolution scan vertices. Note that high-resolution scans have been scaled to the real height of scanned persons. The mean per-vertex error is 0.16 mm. We also visualize the registration quality in Fig. REF . To evaluate the body pose, we compute the per-joint error as the L2 Euclidean distance between 3D keypoints and 3D joints of registered SMPL on the dynamic sequences. The mean per-joint error is 38.18 mm. Note that the error is largely attributed to the difference in the joint definition of the keypoint detector and the parametric model. As a reference, registration with an accurate optical marker system [1]}, [2]} yields a per-joint error of 29.34 mm.
